I am just about to launch my site. I am launching it completely ad free. I am doing this for a few reasons. First, the site looks cleaner. Second, people may be more inclined to use the site if there aren't flashing ads coming at them. Third, who would advertise on a site with little traffic.
My question is, what would be a good benchmark for traffic to a site before I should start putting ads on the site. 100 view per month seems really low, 1,000,000 seems really high. Is there any links to studies, companies requirements, personal experiences you can recommend?
